Abstract (en)
A hermetically sealed twin rotary compressor (10) is disclosed wherein a pair of rotary vane compressors (44, 46) are synchronously, coaxially coupled to respective axial ends of a drive motor (22) by means of a quill (32) disposed in a rotatable rotor (26) thereof. The rotary compressor crankshafts (48, 50) are coupled to the quill (32) with their eccentric portion (58, 58a) oriented opposite one another with respect to the axis of rotation. Counterbalancing weights (60, 60a) are mounted to the motor end rings (62, 62a) oppositely the adjacent eccentric portion (58, 58a) with respect to the axis of rotation. A suction accumulator (136) is provided having a pair of tubes (154, 156) extending from fluid outlets (150, 152) on the accumulator (136) to respective fluid inlets (106, 106a) associated with the pair of compressors. The tubes (154, 156) pass through a pair of spaced apertures (166, 168) in the housing and effectively mount the suction accumulator (136) to the housing (12).
